### Describe in Detail

The diagram shows a square of side 8 cm and four congruent triangles of height 7 cm.

(a) Calculate

(i) The area of one triangular face

(ii) The area of the whole shape

(b) What is this shape, which is a net of a solid?

### Explanation

Here,

(a) (i) The area of triangle: , where, h = height and b = base.

So, here, height h = 7 cm and base will be the side of square so base b = 8 cm

So, area of one triangular face =

(ii) The area of whole shape =

So, area of square =

So, area of whole shape =

(b) The shape is the net of a solid. So, it is called as Square Pyramid.

• If there are all equilateral triangles then the pyramid is called as Johnson Solid.
